BENJAMIN TREBILOOOK, OF GLADSTONE, NEWJEB'SEY, ASSIGNOROF ONE-HALF TO JOSEPH W. KELLY, OF HARRISON, NEW JERSEY.

` CYLINDER.

Patented Nov. 24, 1908.

To all whom it may concern.'

Be it known that I, BENJAMIN TREBIL- oook, a citizen `of the United States of America, residing at Gladstone, in the county of Somerset and State of New Jersey, have invented new and useful Improvements in Cylinders, of which the following is a specification.

My invention has relation to improvements in cylinders for steam or other engines, and it consists in the construction and arrangement of parts as will be hereinafter described and particularly pointed out in the claim.

In the accompanying drawing Figure 1 is a vertical longitudinal sectional view of a steam engine cylinder constructed in accordance with my invention, said view also showing the piston and piston rod in side elevation. view of the same.

The numeral 1 indicates the engine cylinder open at both ends and provided with steam ports 4 extending through the body or peripheral portion thereof. `A longitudinal recess 9 of rectangular shape is provided at one end on the underside of the cylinder. Within the cylinder is mounted a cylinder lining or sleeve 5, which is constructed of an equal length as said cylinder 1 and having openings 7 extending through its body portion which register with the steam ports Llof the cylinder, said lining is provided with a rectangular longitudinal recess 9, in one end of its periphery which is of the same construction as the recess9 of the cylinder and registers therewith. A key 8 constructed rectangular shape and of a size equal to both of the recesses 9 and 9 is slidably mounted therein. A head 2, contacts respectively with the lining and cylinder at one end of the structure, and a head 2 contacts respectively with the lining,

cylinder and key at the other end of the Fig. 2 is a transverse sectional structure, and said heads are secured respectively to said ends of the cylinder by means of bolts 3. vThe cylinder is further provided with set screws l() which extend through the opposite sides of the same, the ends of the screws serving to impinge against the. periphery of the lining. I use these set screws for the reason that the diameter of the lining is slightly less than that of the cylinder, hence they prevent wabbling of the lining. A piston 6 operates within the lining and is provided with a rod 6', havinglmovement in the head 2.

I-Iaving thus described my invention, what I claim is v A structure of the character described comprising a cylinder with openings at opposite ends and provided with steam ports, extending through its periphery, a longitudinal recess at one end and on the undersurface of the cylinder, a lining of an equal length as the cylinder and mounted therein and having openings which register with said steam ports, a longitudinal recess in one end of the periphery of the lining which registers with the recess of the cylinder, a key slidably mounted in the longitudinal recesses of the cylinder and lining a head contacting respectively with the lining and cylinder at one end of the structure, a head contacting respectively with the lining, cylinder and key at the other end of the structure, means for securing said heads to the cylinder and set screws extending through the opposite sides of the cylinder and adapted to impinge against the periphery of said lining, substantially as specied.

In testimony whereof, I aiix my signature in presence of two witnesses.
